concepts for knowledge and learning

I seem to remember professor Hurson informing us that this chapter was dense and boring. Even hard to teach. She was right. I used the above site to  attempt to teach a few people and make sure I understood what was going on fully in the chapter. Out of a group of 6, with all of us contributing and learning together, 2 fell asleep. Tutoring this is kind of boring. But this site gives a lot of history and back tracking to learn a little better. Maybe this will help.
